If tanA+tan2A+√3tanAtan2A=√3 then general solution of A2= · Solve tanθ+tan2θ+√3tanθtan2θ=√3. Anπ+π3. Bnπ2+π6 · If 2tan(π/3)cos(2πx)=√3, the general solution of ... Dec 25, 2023 ... If 3 cot A = 4 therefore cot A = 4/3 tan A = 3/4 to prove (1 – tan 2 A)/(1 + tan 2 A) = cos 2 A – sin 2 A Take LHS (1 – tan 2 A)/(1 + Mar 1, 2018 ... (1+tan^2A)(1-sin^2A) = sec^2A xx cos^2A = 1/cancel(cos^2A)xxcancel(cos^2A) = 1. If 3 cot A = 4, check whether (1 - tan2 A) / (1 + tan2 A) = cos2 A - sin2 A or not. We know that the cot function is the reciprocal of the tan function. Dec 2, 2015 ... Explanation: Use the trig identity: tan2A=2tanA1−tan2A(1). First, find tanA=sinAcosA. ... --> cosA=±45 . ... Check by calculator. Sep 3, 2021 ... Tan 2A - Tan A = Tan A [2/(1-Tan^2 A) -1] = Tan A [(1 + Tan^2 A)/(1 - Tan^2 A)] = Tan A [(Cos^2 A + Sin^2 A)/(Cos^2 A - Sin^2 A)] = Tan A ... Tan 2A=cot(A-15) Or, Tan 2A =Tan [90-(A-15)] Or,Tan2A=Tan(90+15-A) Or,Tan2A=Tan(105-A) This implies, 2A= Oct 27, 2018 ... Trigonometric Identities: Given tan(2a)=2 and 3π2
